The Nervous System II Flashcards
1
Q
Brain development phases:
A
- neural plate induction
- neural proliferation
- migration & aggregation
- axon growth & synapse formation
- cell death & synapse rearrangement
2
Q
What is neural plate development induced by?
A
chemical signals
3
Q
What is the neural plate?
A
a pathc of tissue on the dorsal surface of the embryo that will become the NS
4
Q
Where does neural proliferation occur and at what rate?
A
ventricular zone and can be 250,000/min
5
Q
What do radial glial cells act as?
A
guide wires for the migration of neurons
6
Q
Migrating cells are immature meaning?
A
they are lacking dendrites
7
Q
What is aggregation?
A
Cells that are done migrating align themselves with other cells and form structures
8
Q
A
